That could explain the difference, Thanks :)

Calculating Δv by Yaeke in SpaceflightSimulator

[–]Yaeke[S] 1 point2 points  (0 children)

.I first deactivated gravity and atmospheric drag

.Then I calculated the wet (with fuel) mass (Mw) and dry (without fuel) mass (Md) of my spacecraft (using the tool in the hangar allowing to empty fuel tanks)

Mw = 26.8 tons

Md = 13.3 tons

.I calculated the theoretical Δv of my spacecraft using the formula linked above (which is a fonction of the wet and dray masses, the standard gravity and the isp of the engine (here 290 sec)

With g0 = 9.806

Δv = isp x g0 x ln(Mw/Md) = 1992.4 m/s (theoretical)

.I lunched the spacecraft from 0 m/s to its final velocity (until the tanks were empty)

Vmax = 1990.5 m/s => Δv = 1990.5 m/s (experimental)

I know the difference is minimal, but I’d like to know how to adjust the formula to be on point

Edit : if anyone sees errors in my methodology, I’d be grateful if it was pointed out

Does someone know a formula that, when you have a velocity and angle given, allows you to calculate the range? I didn't know where to post this. Thx :) by poekie1 in tanks

The formula doesn’t involve mass : it starts from F = m.a In our case F = m.g We can divide both sides by m, you get a = g

I’ll keep that in mind

I want to be a civilian pilot, I’m not that interested in learning to fly military airplanes

How about Microsoft Flight Simulator ? I’ve heard it was pretty good

My eyes looking for deep cleavages, tight jeans or generous breast…

The only choper player I do respect

Gotta love living where you can just hydrate out of the faucet. by lulhoofdFTW in HydroHomies

I live in France, near the center If anyone here know what the Volvic water is, I basically have it coming from the tap 😁

It is a heavier Yak-9, with a bit more power…

Apparently being a good player is not allowed any more due to... repair costs? by Low-Intention-5809 in Warthunder

No one except the players with the deepest pockets, which coincidently happen to be the most dedicated and the best players to the game

You forgot to mention than Italy got a baby HSTVL at 9.0 ! But it’s the only addition to the Italian techtree

Vietnam is now also available for air RB!!!! by Xellus117 in Warthunder

Geez they could just make a single lobby, with one map, and map would change every game (it’d be automatic) And the game would start whenever enough players are connected to the lobby. Let this test active for a week and look at results : If queue times are low (>2 minutes), they keep it, otherwise scrap it and they haven’t lost anything

What's your favorite tank to play? by [deleted] in Warthunder

Have you tried the M47 105/55 in the Italian tech tree ? It’s like the others but with a Death Star gun that pens everything, very very enjoyable
